1. MORPHOLOGICAL CHANGES OF FUSE PLUG IN AN EARTHEN DAM DUE TO OVERTOPPING FLOW FROM RESERVOIR
Dr. K. C.Sahu, Dr. P. K. Das, Dr. T. Gangadharaiah
Abstract
Fuse plug works as a safety valve of an earthen dam. It is an earthen embankment, provided to be washout due to overtopping of Flow. The overtopping of flow causes erosion of soil from its surface and the eroded surface of the embankment acts as a board-crested weir. The study on the changes of morphological features during the breaching process of fuse plug helps in the understanding of mechanism associated with the washout of fuse plug. The change in morphology of fuse plug with time controls the breach flow. The location of crest of eroded soil bed profile (Xm) from upstream end of the fuse plug and its height (hcm) are the key controlling parameters to compute breach flow. The height of eroded soil bed profile (hc) is a function of time and space i.e. hc ƒ(x, t), where x is measured from upstream of the fuse plug. The computation of change in hc at different x values in a given time duration help in estimating the soil eroded from the fuse pluge. The reservoir time scale (T*), length scale (H*) and soil resisting velocity (VSR) influence the morphological changes of fuse plug with time of breaching. Keeping these in mind the experiments were conducted on physical model of fuse plug with different soil fills and constant inflows to the reservoir for prediction of longitudinal soil bed profiles in fuse plug during the breaching process.

3. A study on Friction and Wear Comparative Analysis of Three PTFE Composite
Prof. Mahesh C. Swami, Ms. Aarti A. Dyade
Abstract
The present research work is aimed at developing a new material for industrial application. The progress and developments in materials technology have resulted in several new materials. Polytetrafluroethylene (PTFE) is one of them. From literature review it is found that conventional bearing material (Babbitt and bronze) leads to high wear rate as well as high coefficient of friction. Now a day's pure PTFE (Polytetrafluroethylene) is widely used as bearing material which is self-lubricating and subjects to lower coefficient of friction, but problem with PTFE is that, it subjects to high wear rate, which can be reduced by adding suitable fillers. In this study, the effects of varying load, sliding distance, sliding velocity and filler content in PTFE are experimentally examine using a Pin –on –Disc Tribometer. A comparative analysis of three composites ( PTFE + 30% Carbon , PTFE + 30% bronze and PTFE+30%Glass) is presented showing how properties of PTFE can be improved by addition of filler content. The expected results taking into consideration the large number of factors, friction &wear characteristics and optimum bearing construction can be achieved.

6. Improving learning by implementing Scaffolding Constraint
Amarnath Annathur
Abstract
There has been lot of research done in the field of Education and numerous theories have been proposed by highly eminent educational professionals and psychologists. Way of educating/teaching/promoting young people has been changed drastically over the last two or three decades, with the hope that learning could be made better and the pedagogy more efficient. 'Proof of the pudding is in the eating' is a well known proverb. Have the theories and the changes based on them achieved their goals? Are the learners of today better educated than those of yester years? Has the cost of education come down? (as it should have if the learning has become more efficient) Sadly answer to these questions is mostly in the negative in most countries. The change proposed below in educating, using past proven methods will improve the net result and make teaching and learning more productive. Basically it emphasizes that there should be filter at each year to allow only learners who reach a fit level to go to the next year. This will prevent load on the teacher revising previous years topics and going down the ladder to bring up the deficient learners, besides other accompanying benefits.

Abstract
The application of nanoscale materials and structures, usually ranging from 1 to 100 nanometers (nm), is an emerging area of nanoscience and nanotechnology. Synthesis of noble metal nanoparticles for applications such as catalysis, electronics, textiles, environmental protection, and biotechnology is an area of constant interest. lately, an awareness of general sanitation, contact disease transmission, and personal protection has led to the development of antimicrobial textiles. The development of antimicrobial cotton fabrics using Zinc oxide nanoparticles has been investigated in this present work. The ZnO nanoparticles were prepared by wet chemical method and were directly applied on to the 100% cotton woven fabric using pad-dry-cure method. The antibacterial activity of the finished fabrics was assessed qualitatively by agar diffusion and parallel streak method, quantitatively by percentage reduction test. The topographical analysis of the treated fabric and untreated fabric were studied and compared. The results show that the finished fabric demonstrated significant antibacterial activity against in both qualitative and quantitative tests. The SEM analysis discovered the embedding of ZnO nanoparticles in treated fabrics. The wash durability study of the treated fabric was also carried out and found to withstand up to 25 wash cycles.

11. Effects of the Chemical Reaction on Unsteady MHD convective heat and mass transfer past a Semi-infinite vertical permeable moving plate with heat source absorption
Gaddam Venkatreddy, A. Mythreye, Dr. Mani Sarma Vittapu
Abstract
The problem of unsteady, two-dimensional, laminar, boundary-layer flow of a viscous, incompressible, electrically conducting and heat-absorbing fluid along a semi-infinite vertical permeable moving plate in the presence of a uniform transverse magnetic field and thermal and concentration buoyancy effects is considered. The plate is assumed to move with a constant velocity in the direction of fluid flow while the free stream velocity is assumed to follow the exponentially increasing small perturbation law. Time-dependent wall suction is assumed to occur at the permeable surface. The dimensionless governing equations for this investigation are solved analytically using two-term harmonic and non-harmonic functions. Graphical results for velocity, temperature and concentration pro-files of both phases based on the analytical solutions are presented and discussed.
